Q1: Payment Transaction Validation - 2024 Real Question

Problem: Validate payment transactions with fraud detection checks.

Solution (Java):

public boolean validateTransaction(Transaction txn) {
    // Check amount limits
    if (txn.amount > MAX_AMOUNT || txn.amount < MIN_AMOUNT) {
        return false;
    }

    // Check frequency limits
    if (getTransactionCount(txn.userId, LAST_HOUR) > MAX_TRANSACTIONS_PER_HOUR) {
        return false;
    }

    // Check fraud patterns
    if (isFraudulentPattern(txn)) {
        return false;
    }

    return true;
}
